Samsung's drive unfortunately turns in abysmal figures in the WinBench 99 Disk WinMarks, a measure that many still view as the most accurate assessment of hard disk performance. Its Business Disk WinMark 99 score of 5 MB/sec brings up the rear when compared to today's 5400 RPM drives, lagging category-leader Western Digital by over 30%. The margin widens in the High-End WinMark; here the SpinPoint trails the Caviar by nearly 40%.
